Change Settings with User-Friendly Controls

Tekonsha Braken-evn brake controller LED display and buttons

The controls on the BRAKE-EVN are elegantly simple and user-friendly. Use the clearly-marked push-buttons to change the level of gain or boost. Gain lets you set the maximum amount of power that will be applied to your trailer's brakes. Typically, the gain (also known as output) is only readjusted when you experience changing road conditions or if the weight of your trailer changes.

The Tekonsha BRAKE-EVN also features a large LED display that's easy to see so you can check on your current gain setting with a glance, as well as diagnostic information.

Power Boost for Heavy-Duty Towing

The boost setting controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does.

Depending on the level of boost, your trailer brakes can start at either 13 percent or 25 percent of the set braking output. What this means is that, instead of starting at 0, the brakes will start at 25 percent and get to 100 percent sooner. This keeps the trailer from pushing your tow vehicle forward.

If your trailer weighs less than your tow vehicle, no boost is needed. But, if you want your trailer to lead the braking, you can select level B1.

Boost Levels:

Approximate Gross Trailer Weight Boost Level Increase in Initial Power Output
Less than tow vehicle GVW B1 13%
Equal to tow vehicle GVW B1 or B2 13% or 25%
Up to 25% more than tow vehicle GVW B2 or B3* 25%
Up to 40% more than tow vehicle GVW B3* 25%

*Both B2 and B3 offer a 25-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.

To adjust the boost, use the blue push-buttons on the top of the BRAKE-EVN.

Automatic Leveling and Simple Installation

The self-leveling feature of the BRAKE-EVN ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. You can mount it at any vertical angle, and the controller will level itself automatically. But keep in mind that the BRAKE-EVN must be horizontally level and parallel with the direction of travel to work correctly.

Installation of the BRAKE-EVN requires that you either purchase a custom wiring adapter designed to plug into the controller, or that you hardwire the controller directly into your vehicle. To hardwire the controller, you must remove the plug at the end of the integrated wiring harness.

Installation Accessories

For an even easier installation, a vehicle-specific specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

See also's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.

Note: If a custom brake control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

Proportional Braking

What is proportional Braking

The Tekonsha BRAKE-EVN brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.

The BRAKE-EVN uses an internal inertia sensor to detect how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

nice compact controller works great


Insulation was easy and the unit looks good installed. I have not used it pulling a trailer, so I can’t speak to the operation, yet.



Still working great!

@Raymond We're happy to hear that!!


We used this to pull an 18 foot camper through 3 states and back home again. Then we pulled the camper the following year through 2 states and back home again. Steep hills and mountains and hairpin turns were part of our route and this brake controller worked perfectly. Braking was easy and smoothe. Pulling vehicle was a 2022 Toyota Tacoma SR5.


The wiring adapter connected properly to my truck's factory, wiring adapter for electric trailer brake controller. It also subsequently connected properly to the Tekonsha Brake EVN electric brake controller I also purchased from etrailer. Everything worked properly towing my trailer.


Very easy to install and works well to break trailer in conjunction with my vehicles brakes.


This controller works great! Our first season with our new A liner and everything worked perfectly.


you weren't lying. It was an easy to mount and plug and play installation.


Arrived quickly, works well



Works well


During conversion of the 2011 F150 from factory flat-4 to 7-blade, I had already wired for a brake controller, so installation was very simple. I've only towed once since installation, but initial setup was easy and it brakes very smoothly. Great product.


Easy to install. Works great!!


Arrived on time, actually earlier than promised and was a replacement for another controller. Just plugged it in. These controllers work great on an air brake truck


super simple to install and with the purchase of the plug in wiring adapter made sure that everything is correctly connected for long term reliability. Could not be happier.


Wasn't too happy with this unit as it went bad with an (ER) code in less than two months.....Return paid was not happy but We have a new replacement from E-trailer now


Great unit. Was a plug and play on my 99 F250.


This was well packaged and exactly what I was expecting. It will work well for me.


Have bought several items from etrailer and all have shipped fast and been exactly what I wanted.


Easy to install haven't used it yet will update one we start hauling our equipment


My second one for a new tow vehicle. Simple to use and reasonably priced.


very fast shipping and accurate descrip tion


great product


I didn't receive my order yet

Katrina B.


I am sorry that you have yet to receive your order. I see that this order is shipping to Canada. When it comes to shipping internationally, we are unable to confirm the shipping times that you should be receiving your order.


I work for a construction company were always towing something! I've order from here before and I always get exactly what I need faster than expected never fails!


Setup was easy. Worked as expected.



So far so good. I have two of these and they do the job. Easy install.

  • Troubleshooting Overload Condition Code on the Tekonsha BRAKE-EVN Trailer Brake Controller
    When the Tekonsha BRAKE-EVN Trailer Brake Controller # TK63VR flashes the "Overload Condition" code on the display then that means you have a wiring problem on your brake circuit. This can be any of the grounds or the power wires for the brake controller or the brake assemblies themselves so you want to make sure the grounds are secured to a clean, bare-metal surface and that all of the wiring has clean connections and hasn't been damaged - this includes the wiring inside your vehicle and...

  • Does Draw-Tite Activator Brake Controller With no Display Need to be Replaced?
    It does sound like the display on your Draw-Tite Activator II has gone bad and the unit will need to be replaced. We do not carry the Activator II and I highly recommend upgrading to a proportional brake controller, which is going to give you more efficient braking that decreases the wear on both your trailer and Excursion's brakes. If you have been happy with the Tekonsha brand, they offer a proportional controller, the Brake EVN # TK63VR would be a good option.

  • Does an Electric Trailer Brake Controller Drain a Vehicles Battery
    A brake controller, like the Tekonsha BRAKE-EVN # TK63VR , goes into a power-saving mode after being inactive for 15 minutes. It never turns completely off but is basically "asleep" and draws such little power when in this state that it would take months for the controller to drain your Durango's battery.

  • Troubleshooting Locked Trailer Brakes with Activator Brake Controller Displaying No Connection
    Since the Activator Brake Controller 5100 does not have a display chances are that you have another Activator like the IV 5504. When this unit displays a decimal point (and the trailer has no brakes) then this indicates no connection between the brake circuit and the brake magnets. Since your tires are locking up it sounds like you either have a corrosion issue somewhere in the socket or plug or that your trailer connector is wired incorrectly, with the 12V power circuit being fed to the...

    If you install a brake controller like the Tekonsha BRAKE-EVN # TK63VR in your 2017 Jeep Grand Cherokee with the brake controller install harness part # TK93VR you would not need to do any type of programming to the vehicle.

Otherwise you need to hardwire the brake controller to the existing wiring under your driver's side dash.

  • Troubleshooting Draw Tite Activator IV Brake Controller that Only Shows Dot When Brakes are Replaced
    The single red dot on your Draw Tite Activator IV # 5504 normally is seen when you press the brake pedal and a trailer is not connected. When a trailer is connected it normally would start showing the output voltage of the controller. So for some reason your controller is not able to sense a connection to your trailer. What I would first try is cleaning the pins of the trailer connectors as most likely a bit of corrosion is preventing the connection from being made. Try that and also...

  • Is the Power to Brake Controller Supposed to Stay On When Vehicle Is Shut Off?
    After 15 or so minutes of inactivity, the controller goes into a 'sleep mode'. The controller doesn't turn completely off, but the power drain in the sleep mode is so miniscule that it would take months of inactivity to eventually drain the vehicle battery. The fact that the controller doesn't fully shut off is actually a safety feature, so folks don't forget to turn it back on. In other words, your Tekonsha # TK63VR BRAKE-EVN brake controller is operating properly.
